TEST: What happens if the Phantom 4 loses signal and does not have enough battery to Return To Home?

My Ultimate Range Test - Part 3
After my first failed attempt to travel 8kms with the Phantom 4 to my holiday home and land it on the terras there, I want to try it again, but I want to be sure how it will behave if the signal gets lost AND it does not have enough battery to return to home anymore.

So I test this by hovering above the roof of an abandoned shed and then get the signal blocked by a big building.

Eventually I have to land on the roof and retrieve it again. But that turned out to be a lot more difficult than I expected!
